you could play the DS port, thats how ive been playing it.
just get DeSmuME from coolrom, you can simply bind the controls to your SNES controller, since they are the same. you wont have to use the touchscreen at all unless you want to. im pretty sure its essentially the same game with some minor additions

even I have to say Mass Effect, I'm playing 3 right now and by god is it fun! Every character is interesting, with unique personalities, and I will agree with anyone that Garrus is the best fucking character ever
